Footnote: The Order of Prince Henry the Navigator was instituted on June 2, 1960. It is an order of knighthood, created to commemorate the quincentenary of the death of the Portuguese prince Henry the Navigator, one of the main initiators of the Age of Discovery. Minor reforms of the constitution of the Order occurred in 1962 and 1980. It is a five-tier order, whose titles are awarded to individuals and institutions for outstanding contributions to Portugal and for services in the expansion of Portuguese culture, its history and its values (with a particular focus on its maritime history). It is awarded in five grades: Grand Cross, Grand Officer, Commander, Officer and Knight. The number of members in each grade is restricted by its constitution, and titles are conferred by special decree by the Grand Master of the Order, i.e., the President of Portugal.
